Completion scripts should obey the default or customized profile directory

[yarda]

This is related to #872. The bash and later zsh completion scripts should look for TuneD profile in correct directories. E.g. on older RHELs in /etc/tuned and /usr/lib/tuned, on recent RHELs/Fedora/... in /etc/tuned/profiles and /usr/lib/tuned/profiles and should also obey user customized paths in /etc/tuned/tuned-main.conf, the profile_dirs variable.

By "older RHELs," are you referring to versions before 2024/03/25 (commit 90ea23b8b36926253347986535c6801fb09ae47e)? That's when the profile_dirs setting was added to tuned-main.conf, and its value was changed to "/usr/lib/tuned/profiles,/etc/tuned/profiles" the next day in commit 6d3aa949b3a7019bbb70f9bd3b34cb4a9381e8fb (2 commits later).

If that's the case, I can probably resolve this by using profile_dirs's value and defaulting to "/usr/lib/tuned,/etc/tuned."

Edit: I'm only now realizing that profile_dirs is commented out by default, so I'll have to figure out tuned's version anyway -_-
